BURNER.

Application filed August 29, 1923. Serial No. 659,941.

This invention relates to burners, and particularly to a form of burner which is adapted in actual operation to give a maximum heat with a minimum of fuel supply,

to effect a perfect combustion of hydrocarbon liquid or fluid burned, and to ensure a complete combustion without smoke. A further object is the provision of a suitable burner in which an atomizing effect is pro.- duced in the open air at the point of combustion, thus allowing an unlimited amount of oxygen to sustain the combustion. 7

A further object is the provision of a burner which will heat any size of boiler'in a very short time to any desired heat.

A further object is the provision of a burner which is adjustable as to the nature of the fiame. and will either give a spread flame or a jet flame, as desired.

A further object is the provision of a burner in which the parts are not subject to \varpage due to excessive heat.

\Vith the above and other objects in view, the invention consists in the novel and useful provision, formation, construction, asso ciation and relative arrangement of parts, members and features, all as disclosed in one embodiment in the accompanying drawing, described generally, and finally pointed out in claims.

In the drawing:

Figure 1 is a fragmentary side elevation of my improved burner; a

Figure 2 is a fragmentary top plan view of the burner shown in Figure 1; V

Figure 3 is a fragmentary view, certain parts being in section and on an enlarged scale, of the burner,,said view being taken on the line 33 of Figure 2 and looking in the direction of the appended arrows; and,

Figures l and 5 illustrate an adjustment feature of the burner for producing a spread or jet flame.

Referring with particularity to the drawing, the improved burner as an entirety is designated by A, of which a indicates service connections for the burner. The burner in particular has a triangular shaped housing designated by, b and said housing is bored to provide a main fluid supply chamber including the two parallel chambers 1- and 2 separated by a wall 3, the two chambers having a common point of jointure as shown at 4;, and communicating with a port opening 5.. The wall surrounding the port opening may be screw-threaded for the reception of an elbow 6, said elbow in turn being joined with apipe union 7 and from the union to a T 8. One portion as 9 of said T connects with a valve 10 operated through the medium of a handle or wheel 11, the valve opening or closing a port opening 12, said port opening having the walls surrounding the same screw-threaded for the reception of a pipe 13, which pipe in turn communicates with an auxiliary chamber of the burner. The chamber 15 is located above the chambers 1 and 2 and immediately above the partition or wall 3. It will be noted there is a back wall 16 for the burner and that the chambers 1, 2 and 15 communi- I cate directly outwardly with the front wall 17 of the burner. The walls surrounding the chambers 1 and 2 and adjacent the front wall 17 of the burner are provided with tapered screw-threads for reception of adjustment plugs 18 and 19, which adjustment plugs are provided with screw-threaded taper portions 20 and 21 for reception within such screw-threaded openings of the chambers 1 and 2, Stud portions 22 and 23 are associated with the members 18 and 19 and adjacent one face of each of such stud portions there are orifices or openings 24; and 25 produced through the plugs; said openings communicating with the chambers 1 and'2. By reason of the screw threads on the adjustment plugs it is possible to relatively adjust the position of the openings of such plugs, as shown in Figures 4 and 5. The studs 22 and 23 may be termed flame adjustment means, inasmuch as a turning of the same will provide for different forms of flame when the burner is in operation. This type of burner lends itself admirably to the use of either oil or gas, and in the showing a gas arrangement is provided for. If oil were desired to be used, it would be admitted to the auxiliary chamber 15 in regulated amounts, and steam or gas ,or air would be passed through a port openingfi and from thence into the cha1nbers 1 and 2 and from thence through the openings 24 and 25 in the adjustment plugs. Said steam, gas or air would produce a sheet, as it were, of rapidly moving gas or vapor upon-which the oil would drip from the auxiliary chamber 15 and this oil would be immediately atomized and commingled with oxygen of the air to produce heat with perfect combustion, assuming of course that the same wereignited. It is evident that an by this burner.

external atomizing principle is otter-ted. Assuming the position oi the adjustment plugs as shown in Figure l, a spread flame would be produced owing to the position of the sides oi the studs in diverging relation. In other words, the flame would resemble a fan when open, while if the adjustment plugs were turned to the msition shown in Figure 5, the flame produced would be in the form of a being projected straight out without interference by the studs. It is evident that the studs 22 and 23 act to change the nature of the flame, and it is also evident that the close proximity oi the ports 2% and 25 to a surface of such studs acts to direct the flow of any atomizing fluid such as steam, gas or air and control its spread, confining it to certain definite zones. If

were used, such as the showing of Figure 1. would indicate. then the gas supply would be led to the T 8 through suitable pipes and the valve 10 might be so adjusted as to permit a small amount of gas to be passed within the chamber and to burn at the end of such chan'iber, that is, at the front 17 01? the burner in the form of a small taper, acting as a pilot light. It will of course be understood that further adjustment might be provided for the gas flowing to the T 8 and that gas would be forced through the chambers 1 and 2, said gas being ignited by the pilot light. The gas by rapidly flowing through the openings 24 and 25 will be spread or controlled as to the nature o1 the flame of the burning gas b its impingement against the walls of the studs, the adjustment of the plugs controlling such impingement, and the gas will be given a perfect admixture with the air, due to the atomizing eflect produced. The particular burner and its shape, as well as the arrangement oi? the port openings 24: and 25 ot the plugs and the chambers 1 and 2 in a zone remote from the chamber 15 produce remarkable results and a very perfect atomization and combustion is accomplished In other words, if steam, air or gas were being forced under high pressure through the ports 2& and 25 a solid sheet of such gas, steam or air would be presented, and if a hydrocarbon fluid were allowed to drip from the chamber 15, the said hydrocarbon fluid would contact with the sheet aforesaid and be broken up into fine particles and mixed with air to ensure a perfect atomization and combustion. Ap-= parently this principle is far superior to burners operating on the principle of atomization, in which the atomization occurs in ternally and the flow of the burnable fluid such as hydrocarbon is produced by the rapidly flowing gases drawing said fluid in proportionate amounts along with the same.

It is obvious that various changes and modifications may be made in practicing the invention, in departure from the particular showing of the drawing, without departing from the true spirit of the invention.

Having thus disclosed. my invention, I claim and desire to secure by Letters Patent: 1. A burner device including a housing having a chamber for receiving a combustible fluid fuel, a pair of burner plugs fitted in one end of said housing and each having an opening communicating with said chamher, and a flame directing wall formed on each plug adjacent the opening, said walls being adapted to be set in parallel or angular relation to control the shape of the flame. 2. A burner device including a housing having a chamber for receiving a combustible fluid "fuel, a pair oi burner plugs rotatably fitted in one end of saidhousing and each having an opening connnunicating with said chamber, and a flame directing wall torn'ied on each plug adjacent the opening, said walls being adapted to be set in parallel or angular relation by the rotation of the plug to control the shape of the flame. 3. A burner device including a housing having a chamber for receiving a combustible fluid fuel, a pair or burner plugs rotatably fitted in one end of said housing and each having an eccentrically located opening communicating with said chamber, and a flame directing wall formed on each plug adjacent the opening therein, the rotation of the plugs serving to vary the space be tween the openings and also change the angular relation of said walls to vary the shape of the flame produced by the burner.

4. In a device of the character disclosed, a burner member including a housing provided with two interconnected chambers and a third chamber opening at one end of the housing, said third chamber being spaced above said interconnected chambers, and adjustable plug members fitted in the housing below the open end of said third chamber and communicating with said interconnected chambers, and said plugs having means for producing a jet or spread flame.
